first embodiment
[0044]FIG. 2A is a plane view illustrating an organic electroluminescent device according to the present invention, and FIG. 2B is a view illustrating enlarged A part in FIG. 2A according to one embodiment of the present invention. In addition, FIG. 2C is a view illustrating enlarged A part in FIG. 2A according to another embodiment of the present invention.
[0045] In FIG. 2A to FIG. 2C, the organic electroluminescent device of the present invention includes a substrate 300, pixels 30, a planarization layer 320 and a passivation layer 340.
[0046] The substrate 300 has grooves 310 formed at the periphery of an active area in which the pixels 30 are formed.
[0047] The pixels 30 are formed in the active area on the substrate 300 as shown in FIG. 2A. Additionally, the pixels 30 are formed by depositing in sequence an anode electrode layer 100, an organic layer 120 and a cathode electrode layer 140 on the substrate 300.
[0048] The anode electrode layer 100 provides holes to the organic la...
second embodiment
[0064]FIG. 4A is a plane view illustrating an organic electroluminescent device according to the present invention, and FIG. 4B is a view illustrating enlarged B of FIG. 4A according to one embodiment of the present invention. Also, FIG. 4C is a view illustrating enlarged B of FIG. 4A according to another embodiment of the present invention.
[0065] In FIG. 4A to FIG. 4C, the organic electroluminescent device of the present invention includes path extending sections 400, pixels 30, a planarization layer 420 and a passivation layer 440.
[0066] The path extending sections 400 are formed on the substrate 10 at the periphery of the planarization layer 420 as shown in FIG. 4A. Here, the path extending sections 400 have square shape or rectangular shape.
[0067] The planarization layer 420 as a non-conductive organic layer covers the pixels 30. For example, the planarization layer 420 consisted of BCB or SiLK intensifies the adhesive force between the pixels 30 and the passivation layer 440....
third embodiment
[0077]FIG. 5 is a plane view illustrating an organic electroluminescent device according to the present invention.
[0078] In FIG. 5, the organic electroluminescent device of the present invention includes pixels 30, path extending sections 500, a planarization layer 520 and a passivation layer 540.
[0079] The planarization layer 520 and the passivation layer 540 are the same as those in the second embodiment, and so any further detailed descriptions concerning the same elements will be omitted.
[0080] The path extending sections 500 have overhang shape, i.e. the upper base of the path extending sections 500 is longer than the lower base thereof as shown in FIG. 5, and extends the permeation pathway through which oxygen (O2) or water (H2O) permeates. As a result, oxygen (O2) or water (H2O) is not permeated into the inside of the passivation layer 540. In another embodiment, the lower base of the path extending section 500 may be longer than the upper base thereof.
[0081] In addition, ...
